[iPhone] Plot a line chart (like Stocks appl)
Hi all,
I want to plot a line chart like the one that we can see in the Apple Stocks application.
Is there a framework or library or widget that I can use? Or have I to use "raw" Quartz2D functions?
Thank you very much!
There's no specific plotting support in the SDK. There are a number of 3rd party libraries for OS/X, and some of these seem to be in the process of being ported to iPhone. Here's one of the few ports that's ready for download: [http://fluidiphone.com/2008/11/25/ported-phgraph-to-iphone].
You might also take a look at the Google Chart API: [http://pmougin.wordpress.com/2007/12/10/google-chart-api-fun-with-cocoa-and-f- script>.
As mentioned at the fluidiphone link, the AccelerometerGraph sample app at the Dev Center includes a very simple plotting example, but you'd probably need to enhance that code to do very much with it.
Except for the sample app, I haven't tested any of the libraries yet so am just summarizing what's out there, not making any recommendation.
Hope that helps!

Line chart to plot count of 2 date fields against calendar month
Post Author: springle
CA Forum: Charts and Graphs
I would like to create a line chart with 2 lines. I would like the x axis to be a calendar month. I would like the y axis to be the count of a date field for that month. I would like 2 lines, one the the count of applications recieved in a month and the other to be the number of shipments in a month. I can make a chart to plot one or the other but not both on one chart.So in summary I want of a count of date1 and a count of date2 by calendar month in one line chart.Thanks in advance,ScottPost Author: springle
CA Forum: Charts and Graphs
Thanks for the reply but I am afraid this does not solve my problem. Your proposal make the month count of Date1 records in the fields and the count of Date2 in the month of date1 I am try to graph...In the month of Jan: 56 apps and 49 deliveriesIn the month of Feb: 76 apps and 79 deliveriesIn the month of Feb: 86 apps and 69 deliveriesThe change on date cannot be either app date or del date. It needs to be independent from a calendar timeline. Scott -
Plot empty point in line chart with previous non empty value
Hello,
I have a problem to plot series data in SSRS line chart, with the empty point, I don't want use average and zero provided by the report builder, I want use the last non empty data to fill the empty point, tried to use expression =Previous(Field!Value), no
luck, any one have some good idea?
P.S. do not want to use query to fill the null with previous non null value, just from the performance point view. at last , the chart should have some line as square wave with different height, if I use average for empty point, it shows slop wave line which
is not reflect the real production.
Thanks
RichardHi Richard,
In Reporting Services, if the chart type is a linear chart type (bar, column, scatter, line, area, range), null values are shown on the chart as empty spaces or gaps between data points in a series. By default, empty points are calculated by taking the average
of the previous and next data points that are not null.
If we want to use previous value to replace the empty value, please refer to the following steps:
Right-click the field which displayed in Y axis (Height) to open the Series Properties.
In the Value field to modify the expression to look like this:
=iif(isnothing(Sum(Fields!Height.Value)),previous(sum(Fields!Height.Value)),sum(Fields!Height.Value))
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,

Hi, why can't I use the iMessage on my iPhone? I've already had my apple id email on it but it keeps saying "waiting for activation" always like that. No progress. Could anybody help me on this? Cheers
I have an old iPod Touch with old software that can no longer be updated:
iOS version 6.1.6
I've been searching for a solution to my iMessage login problem for months and tried everything from those frustrating links and all the tips from other users.
Here is what finally worked:
1) Settings > Privacy > Location Services > On
2) Settings > General > Date & Time > Set Automatically > On
3) Reboot device until Apple logo appears
4) Settings > Messages > Sign In -

I'd like to buy an iPhone 4S in France directly from the Apple Store, not from the operators. But, I will go back to my country, Thailand. So, I'm wondering to know that there is an INTERNATIONAL warranty for iPhone, and is it valid in Thailand (warranty). Would it be able to be claimed at the iStudio in Thailand?
There is NO International Warranty for the iPhone. Your best bet is to purchase one in Thailand. If you purchase a phone in France, you will NOT get warranty service on it in Thailand and will have to return it to France (or any EU country) for warranty service.

The movies from my Iphone 5 are not coming across on Apple TV. The little spinning beach ball appears like it is thinking. It use to work fine but quick working a month ago. I mirror from my phone to the Apple TV. Still images and everything I do on the phone is mirrored on to the TV except when I want to show a YouTube video or any video and then the screen on the phone and the TV screen go black and the spinning beach ball appears. The videos open right up on the phone if I do not have mirroring on and going through the Apple TV. I just downloaded the latest update to the phone it did not fix the problem. Please help. Thanks, Elvis G
Hello Elvis G,
After reviewing your post, I have located an article that can help in this situation. It contains a number of troubleshooting steps concerning device issues. You may want to consider a reset, then testing to see if the issue is resolved:
Turn your iOS device off and on (restart) and reset
http://support.apple.com/kb/ht1430
How to reset
You should reset your device as a last resort and only if you can't restart it.
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
Thank you for contributing to Apple Support Communities.
Cheers,

I would like to plot two lines with an xy graph in realtime
I understand how to plot in real time with an xy graph appending to an array, but I would like to simply put a line so I can see when my first plot crosses a certain value on the y-axis, say at like y=30. So I would like to know how it is you can plot two lines in real time. I'll put in my vi so you can take a look at what I have so far. On my vi the array is shortened to contain only 5 values so as not to take up memory.

I have made certain modifications to your vi so that now it plots two lines with an xy graph in realtime.

HELLO I WOULD LIKE TO BUY IPHONE 5 FROM THE OFFICIAL SITE OF APPLE BECAUSE IS CHEAPER FROM MY COUNTRY GREECE. MY QUESTION IS CAN SUPPORT THE GREEK MENU OR LANGUAGE? THANKS
To find out what languages are supported, just read for yourself the tech specs:
http://www.apple.com/iphone/specs.html
To find out if you can buy something you have to contact the store yourself. The US Apple store does not sell to other countries. -

Ive purchased a black coloured iphone 5s but i dont like the colour, can apple replace my current phone with a white one?j
If you purchased your iPhone from Apple within the last 14 days then you can return it to switch it for another color if you wish.
If you purchased it through your carrier, then you will need to look at their returns policy, but I expect it would be similar. -

iOS 4.3.5 is not the same as iOS 5. iOS 5 with the new features you list has not been released.
