Hello Nevron Team,

I have a Problem with the BubbleChart from you. I have a List with 4 DataColumns:

1. Title
2. YAxis
3. XAxis
4. Size

I created a NevronChart with the designer. I took the BubbleChart and made the configurations. Now the Chart shows me all the bubbles on the correct positions but the size of the bubbles are always the same (maximum value in the chartoptions "Max Bubble Size"). In case of this I displayed the labels of the bubbles wich have the right number of size ... but the bubbles are with the same size... I don't find anything about this problem so I will be glad if you can help me out.

Best regards

Christopher

Hi Christopher,

We assume that you want to display a XY scatter bubble chart, where each bubble displays a row from your data source - follow these guidelines:

1. From Chart Page -> select Bubble Chart Type and change Subtype to XY Scatter.
2. From Pivot Page -> create a single category with Group By Expression: =Fields![RowIndex]
3. From Pivot Page -> create a single values. The values must have the following Data expressions:

Y Expression: =Fields!YAxis
Size Expression: =Fields!Size
X Expression: =Fields!XAxis

Clicking on the preview page will display a XY scatter bubble. The bubble sizes are interpolated to be in the MinBubble size, MaxBubble size settings. For example: suppose that your bubble chart has MinSize=10 and MaxSize=100 and the data source has Size entries: 1, 2, 3. The first bubble will have size 10 (for value 1), the last bubble will have size 100 (for value 3) and the middle bubble with have value (10 + 100) / 2 = 55.

Thanks for the fast reply,

but unfortunatly this didn't get me any further.
The problem remains. No matter which sizevalue I choose, the chart displays the MaxBubble Size (in your example all bubbles are set to size 100).
On the other hand the x/y value applies correctly.
In my Attachments you'll see the List and the configuration of NevronChart

Your configuration looks OK - please send a saved template file for review. What is there on the category groupings page?

Here is the saved template...
Also I took a screenshot of the category groupings page.

There are two problems with your template:

1. You need to remove the Series Grouping that you have created
2. You may consider removing the Custom Range that you have specified for the PrimaryX and PrimaryY axes.

Hope this helps - questions or comments - please feel free..
You can also see whether the Bubble example shipped with the solution works as expected.
