Data Series
A data series is a chart element that is a data array. A chart is based on a set of data series.
Data series are shown graphically on the chart, for example, as a set of colored columns.
A chart data series which has a name is highlighted in a specific color and an icon specified in the legend.
NOTE. By default, no more than 99 series can be displayed on a chart. If the greater number of series is selected, the first 99 series is displayed, the rest is hidden. To change the maximum number of series displayed on a chart, use registry settings.
Examples of series for various chart types:
To set up chart data series, use the Data Series group of parameters on the parameters panel.
To open the Data Series group of parameters
Parameters button on the toolbar, then select the required group.
NOTE. The number of displayed settings depends on the chart or series type.
By default, the All value is selected in the Series drop-down list for all chart types, except for the following: waterfall chart, stock exchange chart, box chart, and histogram with fluctuation intervals. This value is used to determine settings applied for all series displayed in a chart. Waterfall and stock exchange charts by default display the series, for which the chart was built.
Parameters available for the All series:
NOTE. Parameters available for the All series depend on the chart type.
To set up a specific series, select it in the Series drop-down list. To set up all series, select the All series. Note that the setting determined for the All series do not overwrite the settings determined manually for a specific series.
To apply settings of the All series for all series, including the series with custom settings, click the For All button.
The data series setup panel looks as follows when a specific series is selected:
Set the parameters:
Series Sequence Order
In the Order drop-down list select the series sequence order in a chart. Series numbering starts with one.
NOTE. Changing series sequence order in a chart is available for all chart types, expect for waterfall chartand stock exchange chart.
The order of a series on a chart determines the order of its displaying in the legend.
Setting up the order of series on a chart is also available in the Series Groups group of parameters for histograms of the 
Stacked Histogram with Groups and 
Stacked 3D Histogram with Groups types.
Displaying/Hiding a Series in a Chart
To set up displaying a series in a chart, use the Show in Legend checkbox. The checkbox is selected by default, and a series is displayed in a chart.
NOTE. Showing or hiding a series in a legend is available for all chart types, except for waterfall chart.

Plotting a Series on a Secondary Axis
A secondary axis is an auxiliary value axis, which can display:
Values of data series that strongly differ from other series' values.
Series values presented on the chart as a different data type.
To plot a series on a secondary value axis, select the Plot on Secondary Axis checkbox. After the checkbox is selected, the Value Axis (Secondary) group of parameters is displayed on the parameters panel that is used to set up a secondary axis.
NOTE. Plotting a series on a secondary axis is available for all chart types, except for radar charts, pie charts and waterfall charts.

Trend Line
A trend line is used to visualize data trends and predict their further changes.
The example of a trend line with a one point forward forecast:
To display a trend line, select the Trend Line checkbox.
NOTE. Trend line setup is available only for histograms, histograms with fluctuation intervals, area charts, line charts, mixed charts, scatter charts, bubble charts and stepped charts.
After the checkbox is selected, the trend line parameters setup panel is displayed:
Set the parameters:
Type. Select trend line type in the drop-down list:
Linear. It is applied in simple cases when data series points are located close to the trend line. The linear type of trend line is applicable to the value that increases or decreases at a constant speed.
Logarithmic. The logarithmic trend line describes well the value that increases or decreases quickly at the beginning and then gradually stabilizes. The logarithmic trend line can be used both for negative and positive data values.
Exponential. The exponential trend line is a curved line that should be used when data values rise or fall at constantly increasing rates. However, for the data that contain zero or negative values, this trend line type cannot be used.
Power. The power trend line gives the best results when used with data sets that compare measurements that increase at a specific rate. An example of such a dependency is the acceleration of a race car at 1-second intervals. If there are zero or negative value in the data, power trend line type cannot be used.
Average. The trend line that passes through the data series mean. Such trend line enables the user to view dynamics of changing the considered value depending on the mean value.
Peak Values. The following trend lines are plotted: the line that goes through the maximum value of data series and the line that goes through the minimum value of data series.
Line Type. Select line type in the drop-down list.
Line Color. Select a solid fill color in the drop-down palette or set it in the RGB or HEX format
Line Width. Set the required line width using the keyboard or the value editor.
NOTE. Trend line type selection is available only for two-dimensional chart types.
Use the Show in Legend checkbox to set up displaying of trend line in the legend. The checkbox is selected by default, and a trend line is displayed in the legend.
