Financial Time Series Toolbox

Combine Axes Tool

The Combine Axes tool allows you to combine all axes or specific axes into one. With axes combined you can visually spot any trends that may occur among the data series in a financial time series object.

To illustrate this tool, use dis_nv, the financial time series object that does not contain volume traded data:

• chartfts(dis_nv)
  
  
  

To combine axes, choose the Chart Tools menu, followed by Combine Axes and On.

When the Combine Axes tool is on, check boxes appear beside each individual plot. An additional check box enables the combination of all plots.

Combining all Axes

To combine all plots, click on the check box for Select all plots.

Now click the Combine Selected Graphs button to combine the chosen plots. In this case, all plots are combined.

The combined plots have a single plot axis with all data series traced. The background of each data box has changed to the color corresponding to the color of the trace that represents the data series. After the axes are combined, the tool is turned off.

Combining Selected Axes

You can choose any combination of the available axes to combine. For example, combine the HIGH and LOW price series of the Disney time series. Click on the check boxes next to the corresponding plots. The Combine Selected Graphs button appears and is active.

Click the Combine Selected Graphs button. The chart with the combined plots looks like the next figure.

The plot with the combined axes is located at the top of the chart while the remaining plots follow it. The data boxes have also been changed. The boxes that correspond to the combined axes are relocated to the beginning, and the background colors are set to the color of the respective traces. The data boxes for the remaining axes retain their original formats.

Resetting Axes

If you have altered the chart by combining axes, you must reset the axes before you can visualize additional combinations. Reset the axes with the Reset Axes menu item under Chart Tools -> Combine Axes. Note that now the On and Off features are turned off.

With axes reset, the interactive chart appears in its original format, and you can proceed with additional axes combinations.
