I have this function that make histogram of each Bitmap:
<pre class="lang-cs prettyprint prettyprinted
Code: 
<span class="kwd public<span class="pln  <span class="kwd static<span class="pln  <span class="kwd long<span class="pun []<span class="pln  <span class="typ GetHistogram<span class="pun (<span class="typ Bitmap<span class="pln  b<span class="pun )<span class="pln

            <span class="kwd return<span class="pln  myHistogram<span class="pun ;<span class="pln 
        <span class="pun }
[/code]
Then i have this function that get histogram and make the average of the top <br/>
1000 values per histogram:
<pre class="lang-cs prettyprint prettyprinted

                    counted <span class="pun +=<span class="pln  current<span class="pun ;<span class="pln 

                    result <span class="pun +=<span class="pln  current <span class="pun *<span class="pln  i<span class="pun ;<span class="pln 
                <span class="pun }<span class="pln 
                <span class="kwd else<span class="pln

            <span class="kwd return<span class="pln  result<span class="pun ;<span class="pln 
        <span class="pun }
[/code]
This is the scroll event i want that each time i move to the next <br/>
image/bitmap it will show me the current Histogram of the Bitmap in the <br/>
ZedGraph:

        <span class="pun }

Now this is the function in Form1 that im using when i click the menu it will <br/>
show up the ZedGraph control:
<pre class="lang-cs prettyprint prettyprinted
Code: 
<span class="kwd private<span class="pln  <span class="kwd void<span class="pln  histogramGraphsToolStripMenuItem_Click<span class="pun (<span class="kwd object<span class="pln  sender<span class="pun ,<span class="pln  <span class="typ EventArgs<span class="pln  e<span class="pun )<span class="pln

        <span class="pun }

        <span class="pun }<span class="pln 
    <span class="pun }<span class="pln 
<span class="pun }
[/code]
What i want is to show in some way two modes in the ZedGraph:
<br/>
<ol>
Histogram per Bitmap. The averages of the top 1000 values from each histogram. </ol>
Each mode will be in a different button click event once its showing only the <br/>
Histogram of each Bitmap. And when i close the ZedGraph and click on another <br/>
button it will show me the top averages 1000 values per histogram.
Maybe there is a way to use my text file on the hard disk im creating with <br/>
all the histograms for example:
<pre class="lang-cs prettyprint prettyprinted
Code: 
<span class="pln DANNY VIDEO HISTOGRAM DATA

<span class="typ Frame<span class="pln  <span class="lit 000000<span class="pun :<span class="pln  <span class="lit 17680<span class="pun ,<span class="lit 31263<span class="pun ,<span class="lit 26399<span class="pun ,<span class="lit 20299<span class="pun ,<span class="lit 17361<span class="pun ,<span class="lit 14397<span class="pun ,<span class="lit 12442<span class="pun ,<span class="lit 11780<span class="pun ,<span class="lit 11418<span class="pun ,<span class="lit 11819<span class="pun ,<span class="lit 12180<span class="pun ,<span class="lit 13463<span class="pun ,<span class="lit 15278<span class="pun ,<span class="lit 17829<span class="pun ,<span class="lit 21414<span class="pun ,<span class="lit 25465<span class="pun ,<span class="lit 29902
[/code]
Frame 000000 is Bitmap number one for example and its histogram. Then there <br/>
is Frame 000001 and many numbers wich its histogram. And so on.
But what i want now is to show the histogram of each Bitmap and the averages <br/>
1000 values per histogram. <hr class="sig danieli
