# A vertical line Scatter chart

Vertical line charts are not supported natively in RGraph however they can be achieved using the Scatter chart. With the Scatter chart, unlike the Line chart, you can specify the `X-axis` and `Y-axis` coordinates and a connecting line can be shown as in the example.

Below is the code that's necessary to achieve the vertical line chart. The `Y-axis` labels are specific and used to show the labels for the chart whilst an `X-axis` scale is enabled to show the magnitude of values. The maximum values are set manually - so you may want to add code that determines these based on the data - as a normal Line chart would.

Read the comments in the code sample below to find out more information.

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.scatter.js"></script>

Put this where you want the chart to show up:

    <canvas id="cvs" width="400" height="550" style="float: right">
        [No canvas support]
    </canvas>

This is the code that generates the chart - it should be placed AFTER the `canvas` tag(s):
