Re: TeeChart HotspotTool Function

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.

Re: Responsive (auto-size) charting in .NET website project

Hello, Some formatting end events setup for static charts are not applicable to Javascript charts. Additional, interactive code for javascript charts is normally added via the customcode property of javascript export to run clientside. There are several examples in the webdemo example project.

Re: Javascript / HTML5 teechart flickering/blinking problem

Hello, Yes, the approach I suggested in my last post would have its challenges as you'd need to run the timer refresh routine in the framed chart page, not the container where you have it now. Using TeeChart NET's Javascript export externalcode would be the way to do that, but would take a bit of th...

Re: Responsive (auto-size) charting in .NET website project

Hello, I see a limitation with the use of customcode, that applies universally to each chart in the page (whereas we'd want the scope to run to just the draw method of the chart calling it). We'll take a look at that, In other respects it appears to plot ok. An example attached here for two charts o...

Re: Javascript / HTML5 teechart flickering/blinking problem

Hello, The solution would be to send, once the Charft has been initially loaded, subsequent data directly to the javascript. The ReadData function on your javascript page could call the data directly. ie.. you setup an URL to return the new data, then you can add it by using the javascript series ad...

Re: Remove text after drawing 2D text on canvas

Hello, Everything in OnAfterDraw is called every time the Chart is rendered. If you put boolean conditions in there, like: if myCondition runCustomDrawCode end if then you can control i t being called by setting the condition to true or false ... Calling Chart.Repaint causes the chart to render and ...

Re: Still cannot use palette tool

Hello, I have tried this in a new environment. Runs ok. Is it possible that your test machines are running security software that may be inhibiting the creation of windows objects/handles? Perhaps running the example across several machines may give a hint by more easily identifying what machines ge...

Re: Error: Control 'Chart1' has no parent window

Hello, I can't reproduce this problem straight-off. I created a new VCL Forms project in RAD Studio 11 using TeeChart v2022.34.220329 and added a Bar and FastLine Series using the Editor. I then set the Fastline datasource to Function:Average and the source as Series1. I ran the project and it compi...

Re: Disposing of TChart on Net 6

Hello,

No; if that works ok for you that's fine, ignore my recommendation. I've made a note of the issue I encountered as it may affect other projects with a different buffer setting.

Re: TeeChart for .NET v2022 [14 JUL 2022] RELEASE 2022.7.14

hello, sorry, missed your post here. Thanks for the feedback; TeeChart is using a buffer that is still null and not checked-for when the chart is created and destroyed without a render. We'll fix it. In the meantime you'll need to create some kind of render, export a bitmap to a stream or similar, t...

Re: Set Axis and Zoom in Form Load Wonky

Hello, The chart needs to render before it can run the zoom on what would be the rendered dimensions. You could achieve that this way, removing the call to SetZoom from the initialisation code and adding a one-time call in the Chart OnAfterdraw event: bool hasLoaded = false; private void tChart1_Aft...
