Small rectangle in top left corner of exported chart about highcharts-export-module-asp.net HOT 13 CLOSED

I'm facing this issue too. Apparently this happens for newer highcharts version (like 2.3). With v2.2.5, this doesn't happen.

Most likely another bug with Svg.dll, but if it only recently appeared it
could be worth posting as an issue to Highcharts. Perhaps they can find a
workaround to avoid the Svg.dll bug.

from highcharts-export-module-asp.net.

Yeah. Seems like that.

The box is actually the tooltip. Although set to visibility:hidden it shows up. Even in Inkscape. Older versions highcharts (v2.2.5) were setting the height/width to zero but the latest one (v2.3) seems to set a height/width of 10 which is why it appears.

The workaround is to disable tooltip while exporting

chart.exportChart({ url:'...'}, {tooltip: {enabled:false}});

There are other issues though - such as elongated line on a pie chart for small values.

Fine work! Thanks for sharing your workaround.

from highcharts-export-module-asp.net.

Great. Thanks for the quick response!

The workaround is not working for me. Can you tell me what is wrong with my code?

                       exporting: {
                            enabled: true,
                            buttons: {
                                exportButton: {
                                    onclick: function () {
                                        chart.exportChart(null, { tooltip: { enabled: false} });
                                    }
                                }
                            }
                        }

Disabling tooltips works perfectly, here's my settings:

exporting: {
    buttons: {
        exportButton: {
            onclick: function() {
                this.exportChart({
                    type: 'image/png'
                }, {
                    tooltip: {enabled: false}
                })
            }
        }
    }
}

I have reported issue's description here:
http://highslide.com/forum/viewtopic.php?f=9&t=21294

There is white squire in top-left angle which is not visible on the chart. It's a hidden tooltip.

Also I can see white borders in stackbar charts between stack pieces which are not displayed in component. The 'borderWidth' property in PlotOptions/Column is set to value 0.

Thank you

Is there any progress for this issue?

from highcharts-export-module-asp.net.

Ensure that you have the latest copy of Highcharts. I am not aware of progress on this issue, yet the latest release addressed a very significant number of issues. Please report if it is solved.

Again, I want to re-iterate that rendering issues CANNOT be fixed by this project. This project does NO RENDERING and only supplies the "plumbing" for ASP.NET. It uses the "SVG Rendering Engine" below:

http://svg.codeplex.com/

It is unfortunate that the third-party SVG project seems to have little---if any---ongoing activity. Rendering errors would be best addressed by progress on that project. Short of that, work-arounds might be found via clever coding.

It is possible that the authors of Highcharts might incorporate a simple work-around into their product if it is clearly identified to them. However, I very much doubt they would expend much effort catering to anything beyond the extremely minor.

UPDATE: There appears to be a fork of the SVG.dll project in active development here: https://github.com/vvvv/SVG --- let us know if you try it!

from highcharts-export-module-asp.net.

Please try with this version 76cf6a3 and let us know if it fixes the problem.
