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 support@maqsoftware.com

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 Support@MAQSoftware.com.

Best Regards,
