xTitles Truncate Problem

[bahadirarslan]

Hi,

I implemented MIMChartLibrary to my project but i have a little but disturbing issue.

I am setting an array for x titles values shown below.
clickDates = (
"03/11/2012",
"04/11/2012",
"05/11/2012",
"06/11/2012",
"07/11/2012",
"08/11/2012"
);

But chart couldn't draw all value on chart, only seems a part of value like "03/11/2"
I tried to change xTitleSytle 1 to 4 but nothing changed.

Also changing height doesn't solve problem.

If you can help me i will be appreciate.

I will take a look at it.

Currently i am using xTitleStyle1 but other styles doesn't change the result, too.

Here is the code i am using..

[MIMColor InitColors];
horizontalLinesProperties=nil;
anchorPropertiesArray=nil;
verticalLinesProperties=[NSDictionary dictionaryWithObject:[NSNumber numberWithFloat:15.0] forKey:@"gap"];
yValuesArray=[NSArray arrayWithArray:clickCounts];
xValuesArray=[NSArray arrayWithArray:clickDates];
xTitlesArray=[NSArray arrayWithArray:clickDates];

         lineGraph=[[MIMLineGraph alloc]initWithFrame:CGRectMake(0, mainViewY, 300, 300)];
         anchorPropertiesArray= [NSArray arrayWithObjects:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:@"hideShadow"], nil];
         lineGraph.lineColorArray = [NSArray arrayWithObjects:[MIMColor GetMIMColorAtIndex:0],nil];            
         lineGraph.delegate=self;
         lineGraph.anchorTypeArray=[NSArray arrayWithObjects:[NSNumber numberWithInt:CIRCLE], nil];
         lineGraph.xTitleStyle=XTitleStyle1;
         [lineGraph drawMIMLineGraph];

Hi,

I hope you are using version 2.23 of the library.

verticalLinesProperties=[NSDictionary dictionaryWithObject:[NSNumber numberWithFloat:15.0] forKey:@"gap"];
I think this line is affecting your results. Let me quickly check. and see how I can fix it.
Try increasing that number from 15 to say 25.0
If you want to keep using 15.0 I will be able to take a look at it after some hours.

[ReetuBok]

Ok, Tested quickly with following code and I get following result:

verticalLinesProperties=[NSDictionary dictionaryWithObject:[NSNumber numberWithFloat:15.0] forKey:@"gap"];

yValuesArray=[[NSArray alloc]initWithObjects:@"10000",@"21000",@"24000",@"11000",@"5000",@"2000",@"9000",@"4000",@"10000",@"17000",@"15000",@"11000",nil];

        xValuesArray=[[NSArray alloc]initWithObjects:@"Jan",
                      @"Feb",
                      @"Mar",
                      @"Apr",
                      @"May",
                      @"Jun",
                      @"Jul",
                      @"Aug",
                      @"Sep",
                      @"Oct",
                      @"Nov",
                      @"Dec", nil];


        xTitlesArray=[[NSArray alloc]initWithObjects:@"01/01/2012",
                      @"02/01/2012",
                      @"03/01/2012",
                      @"04/01/2012",
                      @"05/01/2012",
                      @"06/01/2012",
                      @"07/01/2012",
                      @"08/01/2012",
                      @"09/01/2012",
                      @"10/01/2012",
                      @"11/01/2012",
                      @"12/01/2012", nil];


        mLineGraph=[[MIMLineGraph alloc]initWithFrame:CGRectMake(5, 30, myTableView.frame.size.width-20, myTableView.frame.size.width * 0.5)];
        mLineGraph.delegate=self;
        mLineGraph.tag=10+indexPath.row;

        //Set initial Y-Label as 0..
        mLineGraph.minimumLabelOnYIsZero=TRUE;


        mLineGraph.xTitleStyle=XTitleStyle1;

        //Set color for line graph
        MIMColorClass *c1=[MIMColorClass colorWithComponent:@"0,169,249"];
        mLineGraph.lineColorArray=[NSArray arrayWithObjects:c1, nil];


        [mLineGraph drawMIMLineGraph];
        [cell.contentView addSubview:mLineGraph];

In screenshot, the titles seem to be fine..don't go out of bound.. What is it you are doing different?

[bahadirarslan]

I don't know why but changing gap value 15 to 25 solved my problem. Very thanks for your help..

You saved my night :)

Also i wonder can we change text colors on x or y axis?

[ReetuBok]

But this is weird: I ran my test with gap 15 and it seems to work for me.
Which version of lib are you using latest 2.23 ?

Yes changing text color on x y is possible. I will tell you the example where it is done...I will have to find it myself first..

[ReetuBok]

WallChart Example 1.
You can find how to change text colors on x-y axis.

It is also mentioned on the documentation website:
http://mimchartlibrary.blogspot.com/2012/11/other-topics.html

Hope this helps.

[bahadirarslan]

Yes this is very weird because i noticed that sending more values cause this.
For example i am sending values below.

clickDates = (
"10/10/2012",
"11/10/2012",
"12/10/2012",
"13/10/2012",
"14/10/2012",
"15/10/2012",
"16/10/2012",
"17/10/2012",
"25/01/2013",
"29/01/2013",
"08/02/2013",
"17/02/2013"
);

clickCounts = (
38,
1,
1,
7,
1,
3,
2,
4,
1,
1,
1,
1
);

And latest code i used

[MIMColor InitColors];
horizontalLinesProperties=nil;
anchorPropertiesArray=nil;
verticalLinesProperties=[NSDictionary dictionaryWithObject:[NSNumber numberWithFloat:25.0] forKey:@"gap"];
yValuesArray=[NSArray arrayWithArray:clickCounts];
xValuesArray=[NSArray arrayWithArray:clickDates];
xTitlesArray=[NSArray arrayWithArray:clickDates];

         lineGraph=[[MIMLineGraph alloc]initWithFrame:CGRectMake(0, mainViewY, 300, 300)];
         anchorPropertiesArray= [NSArray arrayWithObjects:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:@"hideShadow"], nil];
         lineGraph.lineColorArray = [NSArray arrayWithObjects:[MIMColor GetMIMColorAtIndex:0],nil];            
         lineGraph.delegate=self;
         lineGraph.anchorTypeArray=[NSArray arrayWithObjects:[NSNumber numberWithInt:CIRCLE], nil];
         lineGraph.xTitleStyle=XTitleStyle1;
         [lineGraph drawMIMLineGraph];

Here is the result

I stucked here...

I recently downloaded codes from here and replaced library at project so i could use xTitleStyle enum, because it didn't exist on previous version that i have.

[ReetuBok]

Ok...I understand... I think I understand whats going on now.
The long line chart(when chart is drawn on the scrollview) .. I think the limit of gap in this particular case is 20.0 I guess from what I remember.I had restricted it for some reason .I will try to make it flexible. Thanks for your input.

[bahadirarslan]

Could you suggest me a work around for this to save my night :)

[ReetuBok]

Also I noticed, your y labels start from 1. You can set following variable to start it from 0 if you like.

//Set initial Y-Label as 0..
mLineGraph.minimumLabelOnYIsZero=TRUE;

[ReetuBok]

Ok. Let me take a look for long line chart.

[bahadirarslan]

I changed y label starting and waiting your response about issue with prays :)

[ReetuBok]

Hmm..Interesting.. Now I am plotting the your values which you posted above on 300 px width.. and gap is set to 15px and mLineGraph.xTitleStyle=XTitleStyle1; and it is still looking fine.

My feeling is that you are using a version which probably had this bug for x-y labels which you are experiencing.

[bahadirarslan]

Is there anyway to determine which version i am using?
