how can i make a bar graph in numbers to track trends
I have a table with columns A-K. All the columns have needed data for other things. I need to track trends of incorrect input by staff. Column A has the date and column K has a 1 if incorrect or it's blank if correct. I only need to use the month as I need to track total incorrect for the month to see if there is a downward or upward trend as training progresses. (i need to create a line graph that shows the total incorrect per month) I will be tracking for a long period of time so would be nice if the graph updated as I input more info into the table.
