Hello CanvasJS-Team,
in one of the last releases the tooltip with html-content is broken.
(Switched from v1.9.5.1 GA to v1.9.7 GA)
Testcase:
http://jsfiddle.net/h0jwajxn/
You changed function ToolTip.prototype.getToolTipInnerHTML
These are the relevant lines:
`this.content = toolTipContent;
for (var i = 0; i < this.chart.data.length; i++) {
this.chart.data[i].toolTipContent = this.content;
}`
Fix:
`this.content = toolTipContent || toolTipInnerHtml;
for (var i = 0; i < this.chart.data.length; i++) {
this.chart.data[i].toolTipContent = this.content;
}`
Please add the fix to your code-base, too.
Thanks
