Re: Blazor Chart Cursor Offset

Hello, Dynamic resizing of the Chart can be managed via a resize method such as used here: https://www.steema.com/files/public/teechart/html5/latest/demos/intro/lines.htm (resize window to see chart sizing) See the call: resize(Chart1); code (in demo.js): function resize(element) { if (element != nu...

Re: TeeChart .NET For Blazor Chart does not zoom out correctly

Hello, Ah yes, good point, the clipping zone needs to be restored after this use. ie: dynoTeeChart.ondraw = function() { dynoTeeChart.axes.left.setMinMax(0,12); dynoTeeChart.aspect.clipRect(dynoTeeChart.chartRect); axisX1 = dynoTeeChart.axes.bottom.calc(17.52); axisY1 = dynoTeeChart.axes.left.calc(0...

Re: How to implement dynamic marker functionality on a curve

The applied example in the tutorial I linked shows you how to do that: private void Form1_Load(object sender, System.EventArgs e) { tChart1.Aspect.View3D = false; line1.FillSampleValues(20); } private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g) { if(tChart1.Series.Cou...

Re: How to implement dynamic marker functionality on a curve

Hello, Could you clarify what you mean by dynamic please? ... It is possible to use the OnAfterDraw event (see: tutorial ) but you could add text according to mouse movements or data movements. The image you show suggests something related to Axis label location, whereupon you could use the GetAxisL...

Re: TeeChart .NET For Blazor Chart does not zoom out correctly

Hello, The example code from your earlier post enables both zoom and scroll as 'both' directions. If you require only horizontal, then the C# code for the chart would be: tChart.Zoom.Direction = ZoomDirections.Horizontal; tChart.Chart.Panning.Allow = ScrollModes.Horizontal; That will parse to javasc...

Re: TeeChart .NET For Blazor Chart does not zoom out correctly

Hello, On unzoom, the Axes are resetting to automatic. With only one point in the Chart there is no delimitation to the next point .. it could be infinite. That means that the plotted rectangle has no tangible limit. If you were to plot two points, eg. Series1.data.values=[0.045,0.05]; Series1.data....

Re: Steema.TeeChart.Tools.NearestPoint Change event doesn't trigger

...this has been checked for desktop versions (no problems found) but now notice from other posts you have made, that this issue may be related to Xamarin. Is that correct? ..or MAUI? I see your attached file includes Xamarin installation to the IDE.

With thanks.

Re: help with installation

A temporary workaround that may work is to open the form as text ("View as Text") and remove the following lines from the TeeGrid object definition: _Headers = ( 1 'TColumnHeaderBand' < item end>) If the form is then saved and closed and not reopened as a form it should compile and run correctly.

Re: help with installation

Hello,

Apologies for the delay in replying. There appears to be a problem installing TeeGrid to a form in Athens that may be due to a header error reported on earlier IDEs. We're checking.

Re: Change all fonts

Hello,

There is no property to change all Fonts in one sweep but you can define your own Theme class derived from TeeChartTheme and create your own set of startup values/settings.
