Created attachment 120944 [details] file to test bug When exporting a chart that has no background area fill or some transparency as PNG, the resulting file does not have (100% or partial) transparency conserved, but rather a fixed colour that is the result of the addition of the (more or less) transparent + a white background. Steps to reproduce: - create a chart with some random data - select background of chart, right click, "format chat area" - either remove the colour in "Area" or set a transparency level in "Transparency" - right click on the whole chart, "export as image...", choose PNG format, give a name, save Expected result: - Transparency or absence of background is conserved Actual result: - If colour was removed, the result is a white background - If transparency was set on a colour, result is the addition of the partial transparency on a white background Attached spreadsheet allows to test exporting the charts straight away.
