|
3 |
This example shows a horizontal bar chart.
|
|
|
4 |
As always, the X axis is horizontal, and the Y axis is vertical.
|
|
|
5 |
But the data array contains the X value for each implicit Y.
|
|
|
6 |
The data type 'text-data-yx' indicates this is a
|
|
|
7 |
horizontal plot.
|
|
|
8 |
</p><p>
|
|
|
9 |
This example also has a tiled background image under the plot area.
