Hi Florian,

You can consider using a heat map chart in combination with 2D range bar (that you can use to create the labeled sections). For an example check out the following:
All Examples \ Chart Gallery \ Heat Map
All Examples \ Chart Gallery \ 2D Range Series

This is the case your surface data does not require triangulation - if it does you can still use the range series to create the rectangular sections with the labels, however you need to assign a y value which is greater than the maximum surface value (so that the surface appears below the ranges. In order to achieve interactivity on them you can assign a highly transparent white fill (say with alpha 1) so that the control still thinks the range is filled. Then you can use the HitTest method to obtain the clicked range index.
Hope this helps - let us know if you meet any problems or have any questions.

Hello.
Here is an example image of what I would like to achieve.
After a certain time period, new data should be added at the end of the surface and the oldest data should be removed, creating a flow. The shown Section (A1, A2, etc.) are moved accordingly.
In best case the sections can individually react on click.

Hi Florian,

First of all thank you for your interest in Nevron Chart for .NET.

Can you elaborate on what exactly do you mean by sections - are these sections on the axis or on the chart itself? If they are on the axis you can use a hierarchical scale - for example:
All Examples\Axes\Scaling\Hierarchical Scale.
or you mean something else. We can also schedule a web meeting to discuss this requirement - if you would like to do so just send an e-mail to support@nevron.com with date / time convenient for you.

Hello.
I am currently testing Nevron charts and have a rather specific problem I need to solve in order to consider buying these components.

First I create a surface chart that continously receives data updates. This part should be no problem.
Now I would like this chart to be visually seperated into sections.

Example:
| A1 | A2 | A3 |
|--------------|
|  B1  |   B2  |

I will receive data that allows me to identify which data of the surface chart belongs to which section, so I only need to know how I could realise the display of sections including labels.

Any suggestions would be appreciated.
