Bug in line chart Posts

June 9, 2017 at 5:36 pm Bug in line chart #94249

Participant

Hi,
the line chart (with date-axis) seems to have a bug when there are several data entries at same day.

Please check the following code:
Despite data are ordered ascensing by date and line direction must be only in right direction, the line chart sometimes changes the line direction to left
Look on date:17 Dec 2006, 110 the line jumps backwards and draws the data point twice.

Thank you and best regards
Oliver

Hello oliver13,

Please, change the type of the “date” datafield to the date.

var dataAdapter = new $.jqx.dataAdapter({
	localdata: data,
	datafields: [
		{ name: "date", type: "date" },
