I am looking for information if is possible to change my graph that I can see how my data change by days and months and years (at the momemnt is by days ) ?
The best visulazation for plotting the change in trends is using a Line or a Combo chart. A bar chart can also be used but is ideal if you have only one expression.
You may just use a Line or Combo chart with your calculation expression and add Day or Month or Year as Dimension for the chart.
