Telling the graphs which data should they use

After you set up your data, you will need to tell your graphs which data should they use. The data sources of a graph are defined in the <data_sources> section of the settings file. Different graph types require a different number of data sources. Line, column, step and step_no_risers graphs require only one data source - <close>. OHLC and candlestick graphs require 4 data sources: <open>, <low>, <high> and <close>.

So for the first group of graph types, which require one data source only, the <data_sources> section will look like this:

<data_sources>
   <close>value</close>
<data_sources>

The "value" here is the name of the column that you gave during data setup.

The data source settings example for OHLC and candlestick charts:

<data_sources>
   <open>open</open>
   <low>low</low>
   <high>high</high>
   <close>close</close>
<data_sources>

As you see, the data source and the column names are the same here. This is not mandatory, and might be helpful or confusing in some cases.
