Description
For each series in the output graph, different properties have to be set based on the type of graph. For example, for the vertical bar graph, it is important that you specify correctly the input dataset and the field for plotting values along the Y-axis.
An error occurs if the properties of the graph for individual series are not specified properly.
Solution
Specify the required properties for the individual series.
Ensure that the dataset to be used for the input series is present. Also, any optional properties, if used, should be specified correctly. For example, for the vertical bar graph, if you choose a field for the X-axis, ensure that the field exists in the data.
