Exports a plot to memomy buffer by ggsave #139

Closed fmvin closed 11 months ago

fmvin commented 1 year ago

ggsave exports plot only to a file. Please extends ggsave to export a plot to data buffer.

Hi @fmvin , depending on your needs, you can use PlotSvgExport, PlotHtmlExport or PlotImageExport utility, in a way similar to how they are used in ggsave().

Will this work for you? At least as a workaround.

Hi, just added small demo which uses org.jetbrains.letsPlot.core.plot.export.PlotImageExport utility to obtain bytes of a plot image along with the image dimensions:
