Is it possible to import the entire chart into think-cell?
If the chart is a bar or column chart, extract the numerical data from the chart you see on your screen. Please see Extract numerical data from images in our user manual.
For other chart types, insert a new think-cell chart, copy the values from the datasheet of the other chart, and paste them into think-cell's datasheet. Depending on the old chart's datasheet orientation, copying the data may be easier if you adapt the orientation of the think-cell datasheet as described in our user manual, Transposing the datasheet.
