  • Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
  • Explain what you expect to happen and what actually happens.

Hi, I create a pie chart with data from my DB, I would like to refresh chart automaticly when I add new data to table. It's works because new chart is opening in new windows but I have no idea how to update chart in my program

jade delta
#

there's 2 possibilities depending on the implementation (which isn't shown here)

#

either you're implementing a model/view architecture, and in that case you just have to use the dedicated functions when you're updating the model (probably something like beginInsertData and endInsertData, or maybe beginResetModel, etc, pls refers to the documentation)

#

or you're not implementing model/view arch, and in that case, the component you're using probably have some functions to change its datas

#

if not, delete it and create it again can be a quick workaround
