Error occurs during ACF graph export in Econometric Modeler tool box

Hi,

I am doing multivariate time series analysis in econometric modeler tool box. for the VAR model, ACF plots cannot be exported to plot and shows error. But other graphs can be exported to plot. The error message is follows.

"Error using internal.EconModeler.EconComponents.Figures.ACFPlot/export

Input series must be a numeric vector.

Error in internal.EconModeler.EconComponents.AbstractFigure>@(s,e)this.export() (line 59)

m1 = uimenu(c,'Label',getString(message('econ:econModeler:Export')),'Callback',@(s,e)this.export()); %#ok<NASGU>

Error using matlab.ui.internal.controller.WebMenuController/fireActionEvent

Error while evaluating Menu Callback."

Please help me to rectify this error.

Thanks in advance.

The error message received suggests that input series of the ACF plot is not in numeric format. Few steps which can be taken to check about the input format are:

• Check the format of the input series by making sure that it does not contain any missing or NaN values. One can use the "isnumeric" function to verify that the input series is numeric or not.
• Suppose the input series is not in correct format so then it is required to get it preprocessed or transformed. For example, if the input series is in string format, then it can be converted into numeric with the help of "str2num" function.

These reference links would help in implementing the above-mentioned steps:
