From my experience it seems as if SeriesCollection.Item(index) and LegendEntries.Item(index) are not related. Given a series n how can I remove only the legend for that series? I'm using Office Interop 2010 with Visual Studio 2010. This is easily accomplished via the GUI by selecting the legend entry, then right clicking and choosing "delete". 回答1: To delete a legend entry you have to know the index of the legend you want to delete. Unfortunately, there doesn

Sometimes the series values are zeros or less which is a problem for HighCharts and it throws the following exception: Highcharts Error #10 Can't plot zero or subzero values on a logarithmic axis So as a work-around, I process my ruby array to conditionally replace a zero of less value with an insignificant positive number, .e.g. 0.00001 as shown below: oil_vol_array = d_array[1].map { |e| (e This prevents the exception being thrown, but

That is the chart you want to plot, plot it in the sheet you want. ExcelPackage pck = new ExcelPackage(); ExcelRange r1, r2; var sheet1 = pck.Workbook.Worksheets.Add("data_sheet"); var sheet2 = pck.Workbook

amCharts doesn&#039;t display chart for initially-hidden divs

If I modify the display however, e.g. by resizing the browser or Ctrl-mousewheel zooming, the SVG image is then rendered as expected when the page is redrawn. The exact method of div visibility switching is via Bootstrap's tabbed navbar . I admit to not being very experienced with SVG - is this an issue with
