Need to create 2 line text for pie labels, which can show key on first line and value in second line. Anyway, is there any way to stylize label?

As there is no response from anyone, I tried the following, got success some extend. I am able to create multiline label only, and not the arrow mark.

As i am using typescript following code will helps to create multiline label:. Created plunker. I just used a custom label concanated values but it is of course not inline. But there is a bug - if you hide or show something on the legend, multiline labels disappear becoming standard. Skip to content.

Labels may overlap if the pie chart contains too many slices. One solution is to display the labels outside the pie chart, which may create more room for longer data labels.

If you find that your labels still overlap, you can create more space for them by enabling 3D. This reduces the diameter of the pie chart, creating more space around the chart. You can create and modify paginated report definition.

Each authoring environment provides different ways to create, open, and save reports and related items.

Add a pie chart to your report. On the design surface, click on the pie itself to display the Category properties in the Properties pane. Expand the CustomAttributes node. A list of attributes for the pie chart is displayed. Set the PieLineColor property to Black. The PieLineColor property defines callout lines for each data point label. On the design surface, right-click outside the pie chart but inside the chart borders and select Chart Area Properties.

The Chart AreaProperties dialog box appears. If you want the chart to have more room for labels but still appear two-dimensional, set the Rotation and Inclination properties to 0.

But when the user changes filter value, some of the labels start overlapping. Not that I know of. You can of course drag the labels where you want them and then test all possibilities until you get an acceptable position, but no there isn't any setting to have Tableau do this automatically. Uncheck the "Allow Labels to overlap" box. But of course then overlapping labels to disappear.

Select the portion of pie chart for whom you wish to overlap label onto pie graph. This portion of the pie gets highlighted.

Then drag mouse holding left click over the label. It gets selected. You may now drag and drop it anywhere you want to. I am facing the same issue. Did you find any solution to it and if yes can you please share it here. Hi Sanchit Patel sorry to say but no. With annotate it is similar to MS Excel where it points directly to the slice.

One workaround: 1. It will solve your problem somehow. U have to repeat this process for all remaining divisions in the pie. It should work.

I have my labels outside as I need themI had a similar experience back in Good article, but I have a very weird problem, I'm using nvd3 to show a graph with two sets of data, the user can switch from a set to another, triggering the graph update. Thank you. That is a really good question! I'm not very familiar with nvd3, so I'm not going to be able to give you a straight answer, but If I was troubleshooting the problem, I would look for the point in the initial drawing of the graph when you set up the labels vertically, you will need to set their attributes specifically rotation wise it sounds like you've already done this.

So what you will need to do is perform the same transformation with the appropriate rotation attribute when you update the graph.

I hope that makes sense. I don't know if it will work with your example, because of the differences with nvd3, but if you're still having trouble, post your code onto StackOverflow and ask there. It's an interesting question and I would like to think that there will be someone much smarter than me who will know what to do straight off the bat.

Good luck.

D3 Js Pie Chart Labels Overlap

Cross origin requests are only supported for HTTP. Your zip should have a readme that explains how to get the samples running. Hi Justin, Sorry you're having difficulty. The downloads section is a significant weakness with the information I have on d3.

Deepest apologies. It sounds like you aren't running a web server that will allow you to access the additional file. I kind on rely on folks reading the book in some parts to help them along. Sure is. It's as simple as getting the portion of code that does the rotating in the 'add x axis' part and duplicate it in the 'add y axis part'.

Yow will then need to work out the anchor points, spacing and amount of rotation to suit your graph, but this is pretty simple. Good article.

I am trying to add a horizontal text below the x axis but it is not being rendered. I have added the following code for the xaxis svg. When I add the code that renders the tick labels at an angle, the x axis label text will not be rendered. How will I be able to achieve both display the tick label at an angle AND display the x axis label horizontally below the slanted tick labels. Apologies for the really late reply.

I'm sure that you've figured this out long before now, but I'll answer just in case and if others are interested. Just looking at your section of the code it looks like you have almost combined both the addition of the x axis and the label into a single append.

Thank you so much for this post I know this is an old example but the line You are not accessing the datum or returning a variable to the transform attribute so you could simplify it to. It sure is odd. That's been there for a couple of years! Not just here, but in the book and probably in the example code samples.

Great spotting. I feel suitably humbled that my noobishness has been reinforced. Many thanks I will be correcting directly. And sure enough, it was everywhere.

I tried using the drag method to manually position the label but eventually the same problem happens again with different filters used.

If you manually placing each Status? When I just tested with superstore, as long as I manually placed each when they were all there, then filtered, they didn't go back to the center. I can share the file however it has sensitive data. How can I share it without showing the data source tab? You would either need create a version using a sample data set like SuperStore or check out this tutorial from Joe Oppelt.

Anonymize your Tableau Package Data for Sharing. This was very helpful however it happens again when other filters are selected. Pleases see the attached workbook.

This is an interactive dashboard so click on the "BIS" on the tree map and the overlapping occurs. I have attached the workbook with sample data.

Select "BIS" as filter on the other chart and the overlap displays in the donut chart. I went to the sheet, when I make a selection that puts the "No Response" is outside of the donut, because it can't be selected when it is inside and under the inner viz. From the worksheet, I drag it just a little lower.

Then it stays when I filter and never goes back. If you've done that, maybe it's a version of Tableau you are using. I was not able to open the workbook.

I think you have a newer version of tableau. I tried the same method on mine however when I make other selections and the chart moves, the label stays at the same position.

So sometimes there is a huge space between the chart and the "no response" label. I was able to open it.A common problem related to Pie Charts is the overlapping of the labels that represent data points with relatively small values, adjacent to each other.

By default, the layout engine will try to arrange the data labels so they do not overlap. When the bounds of two or more labels overlap, the engine will move them and their adjacent labels vertically, trying to find them a proper non-overlapping positions. During this rearrangement, a label can be moved aside from its original location, which may produce a hard to read chart.

Additionally, if the plot area doesn't provide enough space and there are a lot of data points, the labels will overlap. To avoid label overlapping and keep your chart readability, you can setup the graph following the steps below. The Pie chart uses BarSeries to represent the "pie slices".

When the alignment is set to OutsideColumnthe data point labels are aligned in two columns around the pie and their offset is controlled by the DataPointLabelOffset property. If the labels needs to be adjusted so they do not overlap, their position might not be aligned against the corresponding data point.

In this case the data point connectors can be setup to provide visual aid to determine the relation between the label and a data point.

In Design view click on the chart series. The Properties Window will load the selected series properties. Set the value of the DataPointLabelOffset property to a value, providing enough offset from the pie, depending on the chart size i.

Also, for better design experience, the connector is drawn only when the distance between the data point and the label is more than one line spacingmeasured by its label's font. If needed, you can also adjust the connector offset using the Padding property. The Bottom represents the offset from the pie, and the Top represents the offset from the label.

The Left and Right values are not respected. Additionally you can set the LineColor and LineStyle according to your needs. When applied on another series type or Cartesian coordinate system, the engine falls back to OutsideEnd value. The algorithm that moves the data point labels, preventing them from overlapping, is activated only when the labels have their DataPointLabelAngle set to a multiple of degrees i.

In an ordinal scale, the order is of utmost importance and not the difference. In the above example, the color variable will act as a scaling function which will return specified color for the specified index. For example, color 0 will return 4daf4a, color 1 will return eb8 color 2 will return ff7f00 and so on. If a value at the specified index does not exists in the specified range then it will restart from 0. You can read more about ordinal scale here. It calculates the start angle and end angle for each wedge of the pie chart.

These start and end angles can then be used to create actual paths for the wedges in the SVG. In the above example, we defined a d3. This function calculated certain fields for the pie chart like startAngle and endAngle along with the data values. These are the paths that will create our pie's wedges. Arcs need an inner radius and outer radius.

If the inner radius is 0, the result will be a piechart, otherwise the result will be a donut chart. We need to supply these generated arcs to our SVG path elements.

We first define all our variables like width of the svg and, height of the svg. We calculate the radius as Math. For this, we choose whichever of the width and height is the minimum value. The above code appended a group element to our SVG to group all the pie elements together. Next, we define our color scale as an ordinal scale.
