I've got these weird marks on my RGraph x-axis. Any idea what's causing it?
Here is a screenshot (I marked the unwanted marks with red arrows)
Here is my JavaScript code that prints the line.
function PrintLine(labels, tooltips, data, color, legend) {
var line = new RGraph.Line(CANVAS_ID, data);
line.Set('chart.labels', labels);
line.Set('chart.background.grid.hlines', false);
line.Set('chart.background.grid.autofit.numvlines', labels.length-1);
if(legend[0].length > 0) {
line.Set('chart.colors', legend[0]);
line.Set('chart.key', legend[1]);
line.Set('chart.key.position', 'gutter');
line.Set('chart.key.position.gutter.boxed', false);
line.Set('chart.key.position.x', 400);
}
line.Set('chart.tooltips', tooltips);
line.Set('chart.shadow', true);
line.Set('chart.ylabels', false);
line.Draw();
}
It looks as though you may have a previous chart staying around - which you can get rid of by clearing the ObjectRegistry:
RGraph.ObjectRegistry.Clear();
将线设置chart.numxticks调整为所需的X刻度线的数量。set('chart.numxticks',n)
