    Hello Anonymous,

     

    Please ensure that you have the latest version of Power BI installed on your system.

    On downloading the sample file, you should be getting a prompt message box as shown below.

    Click ‘Install’ button on the message box. It will install required packages automatically.

     

     

     

    If the message is not visible, please install the required R packages by running the below commands in RStudio or any other R tool installed on your machine:

    install.packages("ggplot2")

    install.packages("plotly")

    install.packages("scales")

    install.packages("htmlwidgets")

    install.packages("XML")

    install.packages("ggrepel")

     

    After installing above packages, the visual will work fine on your system. 

     

    Please get back to us, in case the issue still persists. We can be reached at [email protected]

     

    Thanks!!

Hi Anonymous,

 

Slope Chart by MAQ Software is a custom visual built with R. If you open this custom visual in Power BI Desktop, you may need to install additional R packages and/or an R engine. From the error message, it seems you need to install package plotly and ggplot2. 

 

As this is a customer visual, I would suggest you contact the author via [email protected].

 

Best Regards,
