Dear Sir:

We cannot use the HotspotTool function described on the website in WebForm.
Are there any requirements to use this feature?
We have TeeChart for .NET Standard Business Edition license.
Or is there a demo code for reference?

Hello,

There is some demo code here:

https://github.com/Steema/TeeChart-NET- ... dDrillDown

That is a Pro project but the functionality/code is applicable to the standard version.

....there's a live example of that here:

Dear Sir,

1.In the JScript page generated by using TeeChart .Net version, the JavaScript file path to the website will be automatically generated.
Because our internal network cannot connect to external web pages, can we download and use the files from the website?
(PIC-1)

2.We purchased TeeChart .Net business version contain JavaScript. Can we use the JS files on the website?
For example, the files in the following paths:
https://www.steema.com/get_file/42faff5 ... b22ae3c1a6
https://github.com/Steema/TeeChart-JavaScript-Samples

3.We asked before that the HotspotTool function is only available in the Pro version. What are the differences between the Pro version and the Business version?

4.When using TeeChart, we found that there will be conflicts when multiple people execute the same program at the same time.
Is this an limitation?

Hello,

1. Yes, you may download and source the teechart javascript pages locally. Use the "Export.Image.JScript.SourceScriptPath" property to modify the location looked for by TeeChart.

2. Yes.

3. An overview of the differences between versions is listed here:
https://www.steema.com/feature_matrix/net

Most specialist Tools, including the web Hotspot tool, are not included with the TeeChart Business version.

4. There should not be a problem using multiple client instances of the TeeChart WebChart but we did find an issue recently that we investigated and are testing a fix for, that affects custom code for multiple charts on one page. We will include the fix with the next update and will widen our test scenario to check whether it covers the issue you are reporting. I assume it refers to the use of the Javascript format chart.

When using JScript, the X label is normal when the angle is 90, but the angle setting 270 will error.
Please advise.

System.IO.MemoryStream ms = new System.IO.MemoryStream();
Steema.TeeChart.TChart.Export.Image.JScript.Save(ms);

Hello,

I believe this has been resolved in the latest code. I'll check that is the case and when the fix is to be published and get back to this thread.

Hello,

The public version of TeeChart for Javascript now includes a modification to help resolve the incorrect plot of 270º aligned axis labels.
