SSRS - Replace the Chart - sql-server-2008

Question

I have a question, want some assistance.
Q) My question is that i have a chart in which analyst assigned for many incidents and some analyst have 1 or two incident assigned. just because of this the bar chart looks ugly some time. So thats why i used a new chart to represent Min incident count. But i want there some creativeness, for which i want there a radio button or OnClick event ( I do not know how to use both these. When report runs by default it`ll show Max incidents count chart and when we used radio button it will show Min incidents count chart, on the same chart area no need of new area or on new page.
Kindly help me or refer me some links and with ideas. As i have searched many blogs but i didn`t get any big achievement.
Below is my Simplified query;
SELECT
Count(IncidentDimvw.Id)
,UserDimvw.FirstName AS Analyst
FROM
IncidentDimvw
FULL JOIN WorkItemDimvw
ON IncidentDimvw.EntityDimKey = WorkItemDimvw.EntityDimKey
JOIN WorkItemAssignedToUserFactvw
ON WorkItemDimvw.WorkItemDimKey = WorkItemAssignedToUserFactvw.WorkItemDimKey
JOIN UserDimvw
ON WorkItemAssignedToUserFactvw.WorkItemAssignedToUser_UserDimKey = UserDimvw.UserDimKey
WHERE
WorkItemAssignedToUserFactvw.DeletedDate IS NULL
GROUP BY
UserDimvw.FirstName
Having (Count(IncidentDimvw.Id) = (#Count))
Having Clause is right or wrong, i donot know.
I used the following expresion in series as you suggested.
=iif(Parameters!Count.Value, Max(Sum(Fields!ID.Value)), Min(Sum(Fields!ID.Value)))
Sample data is as folows;

Answer 1

I can think of a couple of ways to approach this:
Dynamic expressions based on parameter
Say you have a simple DataSet like:
And also a boolean parameter called showMax.
We can create a simple bar graph based on this:
The most important thing to note is that Series value is expression-based:
In the above example the expression is:
=IIf(Parameters!showMax.Value
, Max(Fields!value.Value)
, Min(Fields!value.Value))
i.e. when showMax is true, report the Max values, otherwise report the min values.
In this case I've also updated the Axis title, Chart title, and Custom legend text to be expression-based:
Axis Title: =IIf(Parameters!showMax.Value, "Max", "Min")
Chart Title: =IIf(Parameters!showMax.Value, "Max per group", "Min per group")
Custom legend text: =IIf(Parameters!showMax.Value, "Max value", "Min value")
The chart behaviour changes based on what parameter is selected as required:
Set Visibility based on parameter
Another option is simply to have to charts and hide one depending on parameter selection.
For example, for the Max chart the Hidden property can be set to:
=Not(Parameters!showMax.Value)
Setting this property correctly for each report will mean only one is ever displayed to the user, i.e. it will look dynamic.
Either of these options should work; the first keeps the layout simple in the designer makes the chart more complex, the second makes the layout more complex but keeps the charts simple.
Hopefully one option will work for you.
