ear Gents,

I have a dynamic 3d matrix (sensor,time,value) to be plotted in color (value) like a waterfall. Using Tchart (Colormap) is really slow (in theory the matrix refresh rate can be up to 50 Hz) and hung the application. Have some suggestion how to do it or library to be used ?

Thanks a lot

Try pl_ExControls Package

-TplLedBar
-TplLEDIndicator
-TplPlotChart
-TplLogGraph
-TplSimpleChart

Hi Matis,

I need something like heatmap. for any x,y on grid we need the cell with proper color. possibly smoothed.      

I think OpenGL or DirectX APIs can do this
Look at
pl_OpenGL pkg

-TOpenGLCanvas
or
-OpenGL_Engine2D.pas (MS Win Only)

And look at CodeOcean demos

  Thanks Matis,another question. Using Cindy Colormatrix I can solve but I need to convert data value to color. I have a Tlistchartsource (from previous setting) with color palette (list of value -> color), but I can't understand how to convert data value to relative color according palette.Suggestion ? Is possibile to use Tlistchartsource to extract color ? If not how I can create a palette to extract relative color from data value  ?Regards

Hi All,

somebody know if there is some components in order to select color palette shader for matrix ? Like attached image
