I have issue with export SciChart to Bitamp. I have to generate pdf report from data. Report contains two charts.
It is possible to render chart in memory and export to bitmap? I know it is possible in WPF but I couldn’t achive this in Android.
Now my solution is that I render this charts on fragments and wait 1s on each to render and then save chart. But this solution is not good. For slower devices chart is not exported correctly.
For example on one device have strange grid (only exported bitmap, fragment with this chart looks good):
I’m trying to export my graphs using the XamlRenderSurface and the ExportToXPS extension function.
I can export a BitmapImage from it fine but the xps image only has the Axis lines and a vertical annotation on it. See images for comparison.
Also, it outright crashes in some other graphs I have on Get MinorDelta because of a null reference exception, no additional info is given out by DebugWhySciCharDoesntRender = true. Likewise in this case, I can export to bitmap just fine. I am using custom tick providers.
I should also note that I’m rendering the charts from memory they’re not visually displayed when export them.
is there a way on iOS to export a SciChartSurface to a vector format in order to embed the exported chart into a PDF document? Right now the only thing I can find in the Documentation is
exportToUIImage(). If not – any ideas for a workaround until such feature is implemented?
On our SciChart’s XAxis we are using a NumericAxis and within the NumericAxis we bind to a LabelProvider. In the UI, this works perfectly and we get the XAxis appearing with the titles we desire (as strings writing over the numeric values 0, 1, 2, …). Meanwhile the YAxis doesn’t use any LabelProvider and stays numeric. The XAxis.LabelProvider is an IList of strings.
Although this works great in the UI, when I export the SciChart it does not pick up the LabelProvider and the exported image only contains the numeric values 0, 1, 2, … on the XAxis.
I do the export as following:
SciChartSurfaceBase.ExportToFile(filename, SciChart.Core.ExportType.Png, useXamlRenderSurface, exportedSize);
Is there a way to get the ExportToFile command to acknowledge the LabelProvider is there like it does with the UI?
I want my HeatmapColorMap to be part of my chart, so that when I export it, the HeatmapColorMap is visible on the PNG / XPS.
In order to this, I put the HeatmapColorMap inside a CustomAnnotation.
I can see it nicely on my Surface but when I try to export it as XPS or as PNG with some specific size, the numbers and ticks have disappeared, only leaving the rectangle with color gradient (see attached picture)
Is there a way to solve this ?
Thank you !
