This content is checked by fx-9860GII (OS 2.04) and fxCG20 (OS 2.00).
This is on-going project and any changes may be made.
Model
fx-5800P, fx-9860GII and fx-CG20/10
Description
- fx-9860GII or fx-CG20/10 has Text Screen and Graphics Screen. Those 2 screens are switched to each other, and text and graphcs cannot be displayed in a single screen.
- Text Screen of fx-5800P has 4 lines and 16 columns display area. Text Screen of fx-9860GII and fx-CG20/10 has 7 lines and 21 columns display area.
- UNDOCUMENTED Graphics Screen of fx-9860GII has 127 pixel x 63 pixel display area. Graphics Screen of fx-CG20/10 has 379 pixel x 187 pixel display area.
Note
- UNDOCUMENTED For correct bitmap output with ViewWindow setup, user should be aware of the correct pixel numbers of graphics area. For example a bit map output should have problem if ViewWindow 0,126,0,0,63,0 is set instead of correct setup ViewWindow 0,127,0,0,62,0, See below in details;
| Codes | Result |
| ClrGraph CoordOff GridOff AxesOff LabelOff ViewWindow 0,126,0,0,62,0 For 0→Y To 62 SketchDot F-Line 0,Y,126-MOD(Y,2),Y Next |  |
Example 1-2: Unexpected horizontal line appares with wrong ViewWindow seetup (fx-9860GII)
| Codes | Result |
| ClrGraph CoordOff GridOff AxesOff LabelOff ViewWindow 0,126,0,0,63,0 For 0→Y To 63 SketchDot F-Line 0,Y,126-MOD(Y,2),Y Next |  |
| There actually are 63 pixels in vertical direction, but 64 dots is rogically defined in vertical. Psition of all plots are calculated and rounded to be one-to-one correspondence with LCD pixels. That's why the unexpected horizontal line appears. | |
With fx-CG20/10, ViewWindow 0,126,0,0,62,0 and ViewWindow 0,126,0,0,63,0 gives similar but different results.
Example 2-1: Correct bitmap output as expected in code (fx-CG-20/10)
| Codes | Result |
| ClrGraph CoordOff GridOff AxesOff LabelOff ViewWindow 0,126,0,0,62,0 For 0→Y To 62 SketchDot F-Line 0,Y,126-MOD(Y,2),Y Next |  |
Example 2-2: Unexpected horizontal line appares with wrong ViewWindow setup (fx-CG20/10)
| Codes | Result |
| ClrGraph CoordOff GridOff AxesOff LabelOff ViewWindow 0,126,0,0,63,0 For 0→Y To 63 SketchDot F-Line 0,Y,126-MOD(Y,2),Y Next |  |
| Logically it's same result but fxpCG20/10 has different number (187) of pixels, so the result in detailed is not same. | |
