3. Introduction Xcos is an open source graphic simulator by Scilab
Xcos is equivalent to MATLAB Simulink
Xcos on web is browser version of Scilab Xcos

4. Limitations With Earlier Version
No two way communication for TK Scale
No dynamic generation of graphs
Modification of block parameters not reflected in output

5. Limitations With Earlier Version
Some blocks could not be dragged
Disappearing of block images
3-D graphs not available.
No option for downloading graphs and simulated xcos files.

6. Features Implemented
Functionality for following output blocks was implemented :
CSCOPE
CMSCOPE
CSCOPXY
CSCOPXY3D
CANIMXY3D
BARXY
Changes in block parameters reflected in output
Display multiple graphs

7. Features Implemented Maximizing size of output
3D-charts implemented for 3D-scopes
Added zooming and exporting feature
Dynamic output generation

8. Sample Output

9. Sample Output

10. Features Implemented
Implemented functionality for following output blocks :
CFSCOPE
CANIMXY
WRITEC_F
WRITEAU_F
TOWS_C
FROMWSB
Change in block parameters reflected in output

11. Features Implemented Block identification implemented
Functionality for file download
Access to workspace variable in same session

12. SAMPLE OUTPUT Desktop vs Xcos on Web

13. TK Scale Block
Slider Widget used to choose a numeric value through sliders.
User can change the input during simulation/runtime.
It has 3 parameters minimum,maximum and normalization.
Minimum and Maximum represents the input range.
Output of the block is the slider’s current value divided by normalization factor.

14. Two Way Communication for TK Scale
Generate the sliders based on number of TK Scale blocks.
The values from these sliders are logged to a file which are updated periodically.
Received data is processed and converted in order to make the graph.

15. Generating Graph from TKScale Values

16. Sample Output

17. Xcos for Textbook Companion
Implemented Generic method to use .xcos file to generate the diagram
Each Xcos file should have a unique ID
Fetch the file contents based on ID number and load the diagram

18. Parser Parser implemented to convert scilab to javascript
User able to change block parameters
Implemented scilab functions in javascript

19. New Functions Implemented
Implemented jetcolormap, interpolation, linspace, set_io and check_io functions.
Error correction in functions
standard_define
scicos_model
inverse

20. Set Scope Parameters

21. Before Implementation After Implementation
Set Scope Parameters

22. Dynamic Display on Blocks
Before Implementation After Implementation

23. Correction of errors Drag and drop of blocks
73 blocks with wrong and improper image display
