  1. In this area, you can change the font size clicking the A+ and A- buttons and select the required type of chart:
    • Line chart - This is the default style, which displays the data points connected by straight lines.
    • Area chart - This style fills in the area below the lines with colors.
    • Column chart - This style displays the data points as vertical bars.
    • Spline chart - This style displays the data points connected by smooth curved lines; useful for showing gradual changes. 
    • Area spline chart - This style creates a spline chart and fills in the area below the lines with colors.
    • Points and averages - This style displays the individual data points along with lines representing the data average. 

  2. Specify the options for the graph on which the chart is plotted:
    • Stacked - This option groups data sets horizontally to facilitate comparison.
    • Stacked 100% - This option applies the relative percentage of the different data points on a y-axis of 0-100%.
    • Show grid - This option shows/hides the grid in the background.
    • Null to zeros - This option transforms null values into 0.
    • Show chart points - This option shows/hides data points. This option is not available if you have selected the Points and averages or Column chart style.
    • Show all series - This option shows the complete series. This process may take several minutes.
    • Acumulate series - This option displays data values in a cumulative frequency.
    • Show legend - This option shows/hides the legend under the chart, indicating the name of the series and its color.
    • Logarithmic axis - This option displays data using a logarithmic scale, useful when there is a large range of quantities.

  3. Click to show/hide vertical stripes indicating where the series have values higher than 0.

  4. Bands created. Select two series in the left area and click Create band to add a new band. You can create several bands, assign them different colors and rename them.
