## Customizing Running Total Line charts
You can customize the appearance of a Running Total Line chart in a number of ways. Many customizations are possible by setting **Chart Properties**. For information about all chart properties, see [Chart Properties](/s/article/360042925394 "Chart Properties"). Unique properties of Running Total Line charts include the following:
Property
Description
Example
General > Show Right Scale
Includes a second vertical scale in most kinds of multi-line Line charts, with or without date or time data. This is useful in situations where you want to display lines with vastly different value increments in the same chart. In the example at right, the left scale shows values in increments of \$20,000 and the right scale shows values in increments of 2. Because two scales are present, both lines can be interpreted independently on their own scales. If there was only one scale, the \$20,000 increments would be used for both lines, so one of the lines would appear flat.
General > Lines on Left Scale
When Show Right Scale is checked, determines how many of the lines in the chart are measured on the left scale. All additional lines are measured on the right scale. If Show Right Scale is not checked, this property does not work.

General > Number of Running Total Series
Lets you choose the number of aggregated series in most Running Total charts. Series that remain aggregated are determined by your chart series order as it appears in your legend. For example, if you had a Running Total Grouped Bar chart and you indicated that you wanted two running total series, the bars corresponding to the first two bar series in your legend would remain aggregated, and all other bars would show their literal values.
In the example, only one series has been selected as a running total series. This is the blue series at the bottom of each stack. All other series are shown with their literal values.
General > Sync Zero Lines
Syncs the zero lines in dual-scale charts with negative values so the "0" values match. For Running Total Line charts, this works only when General > Show Right Scale is selected.
The first example at right shows a dual-scale chart with scales that do not match. The right-side chart is being used to measure sales, which are always going to be positive; hence the scale starts at 0. However, the left-side scale is being used to measure profit, which may dip below 0. In this case the scale starts at -2000. Because the scales do not match, the chart is difficult to interpret.
The second example shows the same chart with the zero lines synced. Even though the other values do not match, the viewer can easily use the zero line as a reference point to interpret the line and bars simultaneously.
Category Scale > Never Use Time Scale
Determines which type of timeline is used in supported charts with time data.
By default, when time data is used in supported charts, such as Line and Bar charts, Domo automatically makes it appear using a date grain appropriate for your data. This is shown in the first example at right, in which the timeline takes date data spanning several months and shows it by month.
If you check this box, however, date data appears as it does in your DataSet. This is shown in the second example at right, in which the time scale uses individual dates, as in the DataSet.
This option is not available for Step Line charts.
Grid Lines > Remove Min/Max/Avg Lines
Removes the minimum, maximum, and average lines that normally display on mouse-over in standard Bar and Line charts.

Scale Marker Range > Minimum Value
Lets you specify the minimum value for a scale marker range in a Line chart. This value makes up the bottommost border of the range in the chart. The example at right shows a typical Line chart in which a scale marker range has been set, with the arrow pointing out the minimum value of the range. For more information, see Adding a Scale Marker Range to Your Chart .
Scale Marker Range > Maximum Value
Lets you specify the maximum value for a scale marker range in a Line chart. This value makes up the topmost border of the range in the chart. The example at right shows a typical Line chart in which a scale marker range has been set, with the arrow pointing out the maximum value of the range. For more information, see Adding a Scale Marker Range to Your Chart .
Scale Marker Range > Color
Lets you select the color for the scale marker range in a Line chart. For more information, see Adding a Scale Marker Range to Your Chart .
—
Scale Marker Range > Show Lines
Determines whether minimum and maximum lines are shown for scale marker ranges in Line charts. For more information, see Adding a Scale Marker Range to Your Chart .
—
Scale Marker Range > Fill Outliers
Determines whether outlier regions (that is, regions of a line falling outside of a scale marker range) are filled in Line charts in which scale marker ranges have been set. The example at right shows a typical Line chart in which a scale marker range has been set, with arrows pointing out the filled outliers.
