Grapher: the order in which entities appear in line charts cannot be changed

[pabloarosado]

Description

When you create a line chart using multiple indicators, you can change the order of indicators so that certain lines appear on top of others. You do that by moving indicators up and down in the "Basic" tab of the grapher admin.

But if you have a chart with just one indicator, and multiple entities, there is no way to change the order in which lines appear. You can choose which entities to show in the "Data" tab of the chart admin, and you can move them up and down, but this does not change the order in which lines appear.

Expected behaviour

Moving an entity up in the "Data" tab should make its line appear on top of other lines. Note that this is what happens, for example, on stacked area charts.

Steps to reproduce

Steps to reproduce the behavior:

1. Go to this chart
2. Click on the "Data" tab.
3. Move entities up and down.
4. See that the order in which lines appear does not change.
