Filter bar chart with 2 row filter

I have added a bar chart and want to apply 2 filter on bar chart or any chart for example I have item name and calculating total month sale (sum) means from day 1 to day 30 on bar chart. I am able to displaying individual item with sum on bar chart but further i want filter that data with another filter like date that means when i select the item it is displaying the total sum on bar chart but it should also display day wise value if I select date from drop down.

Hello @zagadepravinm , and welcome to the KNIME community.
From my view, you would need to explain further on your workflow. But for a single selection value from dropdown:



In order to be implemented you will have to add the option ALL to the dropdown list and handle it with ‘If Switch rules’. There are some other widgets for multiple selection that you may find useful as well.

Let us know for further advice if needed.

Thank you so much for the help.

my main question start from here now as shown in the image its filtering date by date dropdown same like I want to add one more drop down selection to visualize item name date wise on same bar chart

Hello @zagadepravinm
Please find attached an update of the workflow…

As you can observe it is always similar. For this ‘Item Name’ selector, I’ve included the option to select ALL ITEMS in first instance (with an IF SWITCH). Then, you wont loose any functionality about chart display.

For the date SELECT, I’ve implemented an ALL DATES option in the same way, so at the end you will end up with only two selectors.
