Display Image based on cell criteria

Using Visual Studio 2015 and C# here. I have a DataGridView based on one of my SQL tables. I have added in a DataGridViewImageColumn which is blank at the minute.
I need to somehow display an image in this cell based on the criteria which is ;
IF cell = Y then display image, if blank show nothing. I am relatively new to C# still if anybody could point me in the right direction that would be really helpful.
I'm not asking for somebody to write code for me, just if there is a function to go by that will help I can then look in to.
And YES I have of course googled it many times and tried various bits of code amending to fit my criteria / solution, I cannot get any of them to work.

superposing two or more series into one chart in asp.net

I am trying to fetch data from an oracle database and then plot the data accordingly to a chart. It should be relatively easy but the problem is I have to plot more than one field and superimpose them into the same chart. For example there would be four lines in single chart to specify four different fields. So far I can put two/multiple series into one chart with the following code
and the chart looks like this
But I want them to be superimposed on top of each other. I am not really familiar with asp charts so it would be great to have some valuable input on this.
Thanks. The end result should be something like this -
EDIT::: I see what went wrong with the output! So, what I really wanted to know is that those two value in two series will have the same axis or not! I wanted to plot two values with such difference that they couldnt overlap and thought they were using separate axis. So what I am looking for is already here , it was just wrong data values that gave me hard time. The actual figure now looks like -

Inserting a striped line onto an Excel chart through COM Interop

How can we add a striped line to an Excel chart using C#?
I am able to create the chart using c# but I didn't get any clue how to add a striped line.
Please make some suggestions.
Thanks
Try this:
- add a data series with a steady value ( of 50 in your case )
- move the new data series to the secondary Y axis
- synchronize the maximum for both Y axes
- set Chart Type for the new data series to Line
- set the Line Style for the new data series to a dash type
I know this is not C#, but it is C# as much as you question is :)
When I have things like this, what I'm usually doing is I "manually" do all I have to do in Excel recording a macro with all the stuff. Then I just analyze the macro. You will find a lot of useful information there.
Good luck!
