Pushing a datapoint in front

[darkri]

Hello and thank you for this wonderful tool.

I am trying to add a datapoint on the go to the graph and using chart.options.data[0].dataPoints.push({ y: 25 - Math.random() * 10}); works fine when we are adding a new point to the end of the graph.

However should I wish to add a a new point at the beginning of the graph (on x-axis) using the unshift method instead of push the y axis gets draw accordingly but the x axis stays the same and doesn’t take the gap like pushing does.

Any help wpuld be great.

Hi,

In this case you have to assign x value also or you need to increase auto assigned x value for each dataPoints. Please check this example.

Hello again,

I have noticed that when assigning a negative value to x I am getting unwanted values on the x axis (on certain graph widths) however this isn’t the issues with positive number assigned to x values.

This link is a forked version of yours with two graphs, one for negative x values and one for positive x values:

Any help would be great,
