Using bar charts to display data

[Anita_n]

Dear all,

I wish to display this information in a bar chart but am not sure of how to do this properly. I have a tumor type A with different diagnosis dates, sex and the date when this patients were enrolled in a research. 

A set of patients were enrolled in a research program (enrollment_date), it was detected later that these patients had developed cancer (diagnosis date) I want to display these two dates in a bar chart with the corresponding number of cases and sex. 

Any idea how I can correctly do that?

Tumor_type	Date of Diagnosis	sex	Enrollment_Date	Number_of_cases
TumorA	2010	M	2009	4
TumorA	2012	M	2009	3
TumorA	2012	M	2011	1
TumorA	2012	F	2011	5
TumorA	2017	M	2010	2
TumorA	2017	M	2014	5
TumorA	2017	F	2009	1
TumorA	2018	M	2010	7
TumorA	2018	M	2012	1
TumorA	2019	M	2000	2
TumorA	2017	M	2007	2
TumorA	2017	M	2010	1
TumorA	2018	M	2008	3
TumorA	2018	M	2012	1
TumorA	2020	M	2007	9
TumorA	2020	M	2013	2

I'm unsure a bar chart is the best tool for this data. Draw you graph on paper until you're happy with the meaning conveyed by the graph, and then program it.
