Graph after photo is taken

There is usually a Bar-graph showing the amount of space left on the card, and there is also another bar-graph that shows hown much memory left the card has before it stops taking more photos. Either way, thousands of photos can be stored in a single 500gb card alone. But if you're concerned on how much memory is left in a card, you can find out by going to Settings and looking into Memory. It all depends on whether it is a mobile phone with a camera or just a digital camera. Instructions that come with these devices usually explains all about their performances. Good luck.

The histogram is a tool that is useful to the photographer that shows a graph that represents how much color or bright and dark areas are in a photo. If you're looking at a photo that has a larger portion of the histogram graph on the left, it means there's a lot of dark / black tones - and that details in those areas are likely lost. The same holds true if the graph was heavy to the right edge - but it would mean there is a lot of bright or whites. Subtle details in these areas would also be lost. You can use the graph to adjust your exposure so that these details are visible. A wedding dress that lacks the fine lace details because the whites were "blown" (over-exposed) lacks interest when compared to a photo that preserves the details. Here's a link to a site with some great info in general - and about histograms specifically. Check it out.

Tinker with exposure settings to move the large areas of the graph away from the edges - this will show the details. You can switch the histogram off and on as you see fit.

While viewing the photo, press cursor-up/down to cycle through the different views of your photo.

I find it easier to generate the table then look at the graph. Here how you go about it, illustrated with screen capture taken from the newer version of the calculator.
Press the MENU button.
Use arrows to highlight the TABLE application (1st screen).
Enter a function expression in Y1=
And press the function key F6 under the TABL menu tab. (2nd screen)
A table is generated (3rd screen)
Press F5 (G-CON) for a connected graph, or F6 (G-PLT) for a dotted graph.
The graph is shown (4th screen).
Use the Zoom function (ZoomAuto) or any other Zoom or change the window dimensions to suit your needs.

Press up/down on the multiselector to go through the different views of your picture.

You're seeing the histogram, which shows valuable information about your picture's exposure. While viewing, press up/down to cycle through the different views of the picture.

when you are viewing photos try pressing up or down.

A circle is not a function and cannot be graphed in the regular y=screen. You can graph a circle in parametric mode.

To graph a circle in the regular y= screen, you have to graph it in 2 lines on the y= screen. I assume you've solved for y and gotten a square root equation. Remember a square root can be positive or negative. In line 1 of y= screen graph what you've been graphing and then graph the same equation in line 2 but with a negative in front of the equation. You'll get something that looks like an oval since the calculator screen is rectanglular. To make it look more circular (both parts aren't going to connect), press zoom and then select #5 (square).

Bring up the photo on the camera. Press up or down until you get the histogram (yellow graph). When you get this, press up once, and look at the bottom of the screen.
